These objects I accomplish with the device illustrated in theaccompanying drawing in which similar numerals and letters of referenceindicate like parts throughout the several views and as described in thespecification forming a part of this application and pointed out in theappended claims.

In the drawing:

Figure 1 is a side elevation of a container ready for use.

Figure 2 is a section of the cover removed from the container.

Figure 3 is a vertical section of the container with the cover removedand no can therein.

Figure 4 is a side elevation of a modified form of can having a raisedconical top and with a dispensing device attached thereto, parts cutaway, to show a section of the upper portion of one side of the can andone side of the dispenser.

Figure 5 is a view of a can, partially sectioned, used tocontain thecharged water such as may be placed in the type of dispenser shown inFigures 1 and 2.

In the drawing I have shown the can in which the beverage is stored asA, with the liquid shown as B, and the gas as C. A container E is thenprovided for the can which consists of a cylindrical case 5, set on astand 6, and having a cover or lid 1 therefor. This cover I is providedwith securing notches 8 adapted to fit down around lugs 9 on thecontainer case 5 to lock the lid onto the container and the top side ofthe notch 8 is made on a slant Hl similar to the slope or pitch of athread to lock the cover on with downward pressure.

At the 25 top end of the container E adjacent thetop edge thereof I provide a sealing ring 23 of similar composition tothe gasket H to provide a seal around the edges of the can A when in thecontainer E.

Extending from the end of the conduit I3 there 30 is a tube 25 turned upthe side of the container E and held in place by a bracket 26. The topend of the tube 25 is engaged in a control valve of faucet F, saidfaucet adapted to control the flow of carbonated water or beverage fromthe can 35 through the conduit and out of the valve. The control handlesFl provide the means for controlling the valve and a nozzle 21 directsthe flow of carbonated water from the container.

As a means of locking the can A in the con- 40 tainer, other than thefrictional contact with the sealing ring 23 and the gasket ll, I use thelocking cover I which cover is internally provided with a ring 28 ofgasket rubber or like material around the inner top edge thereof to seal45 the top end of the can when it is in place in the container and beingperforated. This ring 28 is tapered down at the lower edge 29 to fitonto the periphery of the container and onto the upper When wishing touse the device, the can A is set in the container and pressed down byhand until the bottom of the can reaches the gasket I! with the rim l9engaged in the groove 20. The cover I is then placed on the containerand engaged with the locking lugs 9 and by exerting pressure on thehandle El the can is then forced down into the groove 20 and thepiercing point or blade l forms a hole in the bottom of the can whichestablishes communication between the interior of the can A and theconduit l3 and tube 25. Thus, when the can is perforated, the gas Cpressing down on the liquid B forces it out of the conduit and tube 25to the valve F from which it may be dispensed at will. When all of theliquid has been dispensed, the can is removed and a new one inserted.

As a modified form of the device to meet the requirements of a cheapertype of device or another form of can, I have provided a dispensingdevice G shown in Figure 4 which consists of a conical cover 30 carryinga gasket 3| therein,

said cover 30 and gasket 3| adapted to engage the top of a can Al. Thetop of the inside flat surface 32 of the cover is provided with apiercing point 33 which point is adapted to pierce a hole through thetop 34 of the: can Al in direct alignment with a tube or pipe 35 todispense the liquid from the can. The tube or pipe 35 is formed on theinside of the can when it is made and is an integral part thereof sothat when the top end is pierced the pressure of the gas Cl will forcethe liquid Bl from the bottom end of the tube or pipe 35 and to thedispenser.

A dispenser valve K is provided on the top of the dispenser in the topof a conduit 36, said valve adapted to discharge the fluid from the tube35, and the conduit 36, through a nozzle 31 into any desired receptacle.

It will be obvious that some other types of tubes may be used to drawthe liquid from the bottom of the can such as making a false conduit inthe seam of the can and other types of cans and dispensing containersmay be used to hold the liquid, the main essential feature of thisinvention being the producing of a canned carbonated water which may becanned in the conventional manner and then dispensing the carbonatedwater through a controllable valve in any amounts desired.

Having thus described my invention I desire to secure by Letters Patent,and claim:

1. A dispenser for canned carbonated water beverage comprising, acasing; a conduit leading from the center of the bottom of said casingand extending up one side thereof to a level above the level of the topof the container in which the beverage is canned extends; a valve in thetop of said conduit; a piercing point mounted centrally in said casingabove the open end of said conduit; a gasket in the bottom of saidcasing extending to the perimeter thereof and having an annular groovenear the perimeter of the casing in which the top flange of the can isadapted to seat when the can is inserted in the casing prior to thepuncturing thereof to prevent escapement of the fluid therearound; and acover for said casing to be secured thereto in fixed relation theretoafter insertion of the canned beverage.

2. A device as set out in claim 1 including a gasket formed inside thetop of the casing against which the top of the can engages.

3. A dispenser for canned carbonated beverages comprising, a casing; aconduit leading from the bottom of said casing and extending up one sidethereof; a valve in said conduit; a piercing point mounted in saidcasing over the open end of said conduit, said point to penetrate thecan permitting the contents to pass into said conduit; a gasket in thebottom of said casing extending to the perimeter thereof; means, byinternal pressure, when the can is in the bottom of the casing, to sealthe top groove of the can, to prevent escapement of fluid; and means tolock the can in the casing.
